Swimming. An ancient aquatic sport. Its is the art of self-movement in water by use of hands and/or feet. Swimming is viewed as a sport or as recreation. Storks and techniques must be learned by humans, as it does not come instinctively. Different strokes and body positions have been developed to enable swimming. More in-depth strokes and movements have evolved for competitive swimming. Swimming basically can take place in any body of water with the capacity to allow free movement and is not to cold, hot, and too turbulent. Currents and tides can make swimming dangerous especially for beginners with little experience.
